Faulty throttle sensor

Check the throttle connector and connecting cable or replace the throttle accelerator.

Check the brakes, brake connectors and connecting cables, or replace the brake lever or throttle brake.

Check whether the brake lever or throttle brake is water-intruded, oxidized and short-circuited. Please replace it with a new brake lever or throttle brake assembly.

Check the throttle accelerator for water, oxidation and short circuit, if the throttle is damaged, please replace the accelerator with a new one.

The repair sequence for this fault check is as follows; shut down, restart and observe whether the problem is eliminated. If the fault still exists, please check whether the communication cable between the display computer and the controller is in good contact. If the communication cable is well connected, please replace the controller and display in sequence until the fault is eliminated.

This fault code is triggered by overloading the motor due to external resistance, simply reduce the load on the motor and the vehicle will resume operation. If the fault is not caused by external overload, please check whetherthe
motor is stuck by foreign objects and whether the bearing is damaged. The fault phenomenon caused by the aging of the motor can be eliminated by replacing the motor.

This is triggered by current overloads under extreme operating conditions, and operation can be resumed simply by shutting down and restarting the vehicle. If the fault is not eliminated after shutdown and restart, the fault can be eliminated in the following order:

1.  Replace the controller with the same model.
2.  Replace the motor with the same model.

The maintenance sequence of this fault inspection is as follows: Shut down and restart, and observe whether the problem is eliminated. If the fault still exists, please check whether the communication cable between the display computer and the controller is in good contact. If the communication cable is connected well, please replace the controller in turn. , display the computer components until the fault is eliminated.

Illegal modification of the battery will cause this failure or connected to a voltage exceeding the original settings. Please install and use the original battery to eliminate this failure.

The battery voltage is lower than the critical value. Please use recommended charger to recharge the battery.

Check whether the connection wire between the controller and the motor is broken and worn, and whether there is an oxidized virtual connection. If there is no abnormality in the wire, please troubleshoot in the following order:

• Replace the original brand-new motor.
• Replace the original brand-new controller until the fault is eliminated.

Check whether the motor.  Hall connector is loose and oxidized, and whether the Hall cable is worn or broken. If there is no abnormality in the cable connector, please replace it with a new original motor.
